So fügen Sie mehrere Ereignishörer in JavaScript hinzu
// events and args should be of type Array
function addMultipleListeners(element,events,handler,useCapture,args){
if (!(events instanceof Array)){
throw 'addMultipleListeners: '+
'please supply an array of eventstrings '+
'(like ["click","mouseover"])';
}
//create a wrapper to be able to use additional arguments
var handlerFn = function(e){
handler.apply(this, args && args instanceof Array ? args : []);
}
for (var i=0;i<events.length;i+=1){
element.addEventListener(events[i],handlerFn,useCapture);
}
}
function handler(e) {
// do things
};
// usage
addMultipleListeners(
document.getElementById('first'),
['touchstart','click'],
handler,
false);
